Branching, making commits, and creating pull requests come easy, but beyond that, I know utterly nothing about it.
I am an Old and we never were taught anything about coding with other people who were also working on the same project. I have had many successful projects but never with another person.
With that as a background, does your guide cover things like:
1) Merging. I was told that merging happens "automagically" and I cannot, for the life of me, understand how a computer program manages to just ... blend two functions or whatever and it "works." Does your guide make sense of this?
2) Apparently there are holy wars (see also vi versus emacs) about the One True Way to ... decide on branches and whatnot. Are there pros and cons laid out anywhere?
3) Everything seems broken down into teensy tiny functions when I look at someone's git repository, just skillions of files all over the place. Is this a git thing, a code repository thing, or simply that, in order for multiple people to work on the same project, everything must be atomized and then reassembled later? What's your opinion?
